Abstract
The widespread use of the insulating mineral oils (transformer) poses a serious risk to the environment, due to its content in toxic organic substances and xenobiotics. Although the synthetic ester oils have a minimum risks to the environment, their use are limited due to their relatively high price. The papers present our preliminary studies on the possible use of the vegetable, natural ester, oils in electric equipments.
Keywords: transformer oil, insulating oil, environmental protection, biodegradability
